DAVID CAMERON LASTnight promised radical change for the Tory Party after being overwhelmingly elected its fourth leader since Labour came to power.

He trounced rival David Davis by a margin of more than two to one, gathering 134,446 votes to 64,398.

Celebrating his victory, the 39-year-old said the Tories must adopt a ‘modern, compassionate Conservatism’.

The new leader said the Tories had to change how they looked, felt and behaved, including no more ‘grumbling about today’s Britain’.¿

The former Shadow Education Secretary added that there was ‘something in the air’ which meant voters were prepared to look at his party again.

‘People are crying out for a Conservative Party that is decent, reasonable, sensible, common sense and in it for the long term of this country and that is the party we are going to build,’ he said. There was still a ‘vast mountain to climb’ but the Tories could return to government, he added.

In a show of unity, Mr Davis said the race had made the party look thoughtful and mature and was the ‘preamble towards the next General Election’.

Mr Cameron swiftly promised that the defeated candidate would be a ‘a vital part’ of his future team.

But he made just one appointment – West Derbyshire MP Patrick McLoughlin became Chief Whip, replacing David Maclean who has a long-standing illness.

Labour spokesman Fraser Kemp said: ‘Cameron is a Conservative and stands for Conservative values. The Tories are putting a new gloss on the same old policy of cuts.’

The result ends a seven-month wait for a leader. Michael Howard said he was quitting after May’s General Election.
